Greenlee lube spreader swabs spread a coat of wire lubricant in a duct
before the installation of cable. They also clean mud, dirt, and light
debris from a duct before pulling. Their tapered shape permits
bi-directional use, and they won't damage the inner walls of your duct. Current also offers lube spreader discs that also act as connectors. The polyurethane discs have angular grooves which allow for better distribution of lubricant.
